US COVID Vaccination Circles
A map of the United States shows the percentage of each state’s eligible population fully vaccinated against COVID-19 as of September 4, 2021, with circle radius proportional to that percentage. Built with D3 v5 and TopoJSON, the visualization uses `d3.geoPath` to render state boundaries and a linear scale to size the circles, which are positioned using state centroids from a JSON file. Vaccination data comes from a CSV of state-level records, and the SVG circles are semi-transparent blue.
